“ Full faith and credit does not here enable one state to legislate for the other or to project its laws across state lines so as to preclude the other from prescribing for itself the legal consequences of acts within it. ”

“ The question is whether the full faith and credit which the Constitution requires to be given to a Massachusetts workmen's compensation statute precludes California from applying its own workmen's compensation act in the case of an injury suffered by a Massachusetts employee of a Massachusetts employer while in California in the course of his employment. ”

“ By the applicable Massachusetts statute, §§ 24, 26, c. 152, Mass.Gen.Laws (Ter.Ed.1932) , an employee of a person insured under the Act, as was the employer in this case, is deemed to waive his 'right of action at common law or under the law of any other jurisdiction' to recover for personal injuries unless he shall have given appropriate notice to the employer in writing that he elects to retain such rights. ”
